This invention, generally stated, relates to a clamp and has more especial relation to a rope, cord, cable, or similar clamp adapted among other things for use in connection with clothes lines, tow lines for motor cars,

and similar connections. l

One object of the present invention'is to provide a clamp which may be used in connection with a rope, cable, or the like, whereby the same may be easily slackened or tightened, and in which therope, cable or the like may be attached with respect to the clamp without the employment of knots. 7 c 7 A further object of the present invention is to provide a clamp ofthe character stated v whereby the rope, cable, or the like may be readily and conveniently inserted with re spect to the clamp in a sidewise manner, thereby eliminating the necessity of threadgzo'ing the rope or cable with respect to the clamp.

A further object of the present invention is to provide a clamp of the character stated the parts of which are so arranged with aarespect to one another that the post plates at all times are interlocked with respect to one another so that danger of one plate becoming separated from the other plate is obviated.

3% A still further obj ect of the present invention is to provide a clamp of the character stated in which a pairot plates are employed one of which is substantially U-shaped in cross section, and the other of which is of -rectangular cross section and is arranged to nest with the plate of U-shaped cross section. Other and further objects oflthe present invention reside in the provision of general details of construction andin the arrangerd-ment, combination, andconnection of parts for attaining the results sought by the 'foregoing objects. a r

The invention consists of the novel construction hereinafter described andffinally '43 t claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying 86* drawings forming part hereof, and in which:

For thepurpose of illustrating. 'myjinvention Ihave shown inthe accompanyingdraw;

in-gs one form thereof Whichis at present pre- 5 :terred by me, since thesarne has been found in practice to give satisfactory and reliable l 5 resu'ltsfalthough it is to be understood that the various instrumentalitiespf which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arran'genrent'a nd or: ganization otthe instrumentalities as herein shown anddescribed.

Referring to the drawings in detail, the I reference numeral 1 designates a plate ofrectangular configuration having" oppos'ed flanges '2 so tha't viewed 'i'n'cros's section the plate 1 is substantially U- shap"ed. The flanges 2 are each provided with vgsha'p'ed notches 3. Disposed opposite the plate 1 is I a second plate designated tv'v'hich is also of rectangular configuration butof smh size that it is accommodated between the flanges 2 of plate 1, as is clearly illustrated in Figs;

1, 2, and :3. In cross section the plate 4 is provided throughout its length with apai'r of V-s'haped, parallel grooves 5, best seen in Figs. t band 6. With the plates 1 and- 4 inclampediposition the V -shaped notche a are in register Withthe V sh-aped grooves f5. The plates 1 andlareso assembled that tneyeon; stitute in efiect-a unitarystructure so that thej. .parts of t'he'clamp as a whole are not liable'to become "detached one from'an'other.

Having screw: threaded relation with plate 4. is a bolt 6. The plate 1 is aper'tured so as to'be free to move with'respectto the bolt In other words, the plate 1 does not have screw threaded relation with'the" boltfti.

Having screw threadedrela'tion with the 6 -i's a'butterfiy nut 7 wherebythe plate'lf ing notched portions arranged for alignment with the notches of said main member, a-bolt'.

may be caused to advance towards the plate 4 so that a rope 8, cable 'or the like, may be clamped between the plates 1 and 4. In the connection it is to be noted that the registering notches and grooves of the respective plates permit of the accepting of ropes, ca bles, or the like, of varying diameter so that a tight grip may be obtained irrespective of the diameter of the rope or cable. This is possible because the smaller plate 4 engages between the flanges 2 of plate 1. It is also to be noted that the rope, cable or the like may be introduced sidewise between the plates 1 and 4 in contradistinction to-thread-.

- ing the rope, cable, or the like endwise between the two plates. Another point is that the rope, cable or the like may be clamped to place without the necessity of employing knots. The bolt .6 is provided. with a head 9 slotted forthe acceptance-of a screw driver so that the bolt may be caused to engage plate 4. In the connection it is to be noted that the head 9 prevents the escape of the butterfly. nut 7 so. that the various parts of the clamp cannot become accidentally detached.

The above described clamp is particularly .adapted for use in connection with clothes lines where a rope may be formed togo around a clothes pole and the ends of the line diverged for attachment to other poles.

.However, the device is applicable for use in connection with tow lines for motor cars, and other uses where a quick clamping of a rope, cable or the like may be efi'ected without the employment of knots.
